Summary

Cars are nowadays by far the most common means of transport, but this popularity leads to safety and environmental problems. One solution to improve safety and driver comfort consists in allowing vehicles to exchange information about events on the road such as accidents and traffic jams.

Ad-hoc networks are wireless networks capable of organizing themselves without any infrastructure. Instead of communicating through a centralized access point, they are composed of wireless nodes communicating with each other to exchange information.

This pilot deals with Vehicle to Vehicle communication, where information is decentralized and vehicles build their own information. It is focused on the high-level aspect of merging and organizing the messages received by a vehicle. To model the uncertainty on each message, the theory of belief functions, is used. Implemented with MatlabTM, the pilot simulates the movement of the vehicles, the events on the road and the messages exchanges. It allows LGI2A Researchers to test different methods to exchange and manage information. An example of a scenario in progress is given in Figure 2.
